Insulating a flat residential roof can be a challenge, but the results are well worth the effort. Once insulation is applied to the wooden sheathing, the roof will be better protected against extreme temperatures, rain and wind. Homeowners can consult with a local Houston roofing service to select the best type of insulation for their residences.

There are many different types of insulating materials that can be used on the surface of a flat roof. One of the leading options is foam core board insulation. This sturdy yet lightweight material is easy and fast to install and can withstand extreme temperatures that are associated with flat tar and asphalt roofs. Spray foam insulation is the other type that can be used on a flat roofing system. Both of these materials must be installed by professionals to avoid any possible roof damage and to ensure that they are installed correctly.

Once a type of insulation has been selected, the next step is to make sure that the rooftop is adequately ventilated. The optimal time to do this is during building construction or when the roof is being replaced. On a flat roof, the ideal place to install vents is on the exterior sides of the building. These openings allow heat from the structure's interior to escape.

A well ventilated roof lasts longer and helps the insulation do its job.

When the roofing is ventilated and the wood sheathing or decking is laid, a moisture proof barrier will be placed on top of it. The vapor barrier also works to repel heat from entering into the structure. The next layer applied to the rooftop will be the insulation.

The insulating boards are nailed into place and then sealed along their seams with a waterproof and heat resistant construction sealant. This helps to protect against the intrusion of water and heat. If spray foam is used as the insulating material, there will not be any seams to seal. Any openings in the rooftop, such as chimney or furnace flues will also need to be sealed to guard against leaks.

After all the insulation is in place, a thick layer of adhesive should be applied across the entire surface of the flat roof. This material will adhere the rubber mats to the roof's exterior face. Because the asphalt based adhesives can dry out rapidly upon exposure to the air, they should be applied in sections as the rubber mats are laid. Additional tar, tar paper and sand can be added on top of the rubber.
